Abstract

PROBLEM TO BE SOLVED: To provide a display control device that can provide adequate information to each occupant considering the difference between a display for driver and a common display for occupants.SOLUTION: When a content is distributed from a center (S140: Yes), the content for a driver is generated (S160), and the content is displayed in a different mode from that of a common display for occupants on a display for the driver (S190, S200). More specifically, when it is determined that the vehicle is running from traveling information to be obtained by a vehicle information acquisition unit (S150: YES), the content for the driver in which the information quantity is reduced from the content to be displayed is generated (S160), and displayed (S190) on the display for the driver.

Description

  The present invention relates to a technique for displaying information that is highly convenient for a driver or a passenger when displaying vehicle information or the like on a display device prepared in a passenger compartment.

  Various display devices for providing information in the interior of a vehicle are mounted. For example, there are a head-up display and a meter panel that mainly provide information to the driver (hereinafter referred to as “driver display”). Some meter panels can display various information graphically by using liquid crystal or the like. In addition, for example, there is a liquid crystal display for providing information to passengers (hereinafter referred to as “occupant shared display”). Specifically, a display on which a navigation map is displayed and a display for enjoying a DVD or the like in the rear seat are the same.

  Conventionally, it has been proposed how to display contents in these display devices (see, for example, Patent Document 1). This technology discloses what kind of content the display screen is configured according to the vehicle surroundings, that is, how to set the display position and size of the content.

Japanese Patent No. 3363935

  However, the technique described in Patent Document 1 is only for one display device, and does not focus on the difference between the purposes of a plurality of display devices, more specifically, these display devices. In other words, “driver display” and “occupant shared display” are different in information recipients, but such differences are not taken into consideration. As a result, if the above technology is applied as it is, information will be provided in the same manner on the “driver display” and “occupant shared display”, and a plurality of display devices with different information recipients will be provided. There is a possibility that it cannot be fully utilized.

  The present invention has been made to solve the above-described problems, and its purpose is to provide appropriate information to each occupant in view of the difference between a driver display and an occupant display. It is to provide a display control device.

The display control device (10) according to claim 1, which is made to achieve the above object, displays contents on a plurality of display devices (50, 60) mounted on a vehicle.
Here, the display device includes a driver display (60) that mainly displays to the driver, and an occupant common display (50) that displays not only to the driver but also to the passenger.

  At this time, the vehicle information acquisition unit (12) acquires vehicle information including vehicle travel information. Then, the control unit (11) displays the content on the driver display in a manner different from the occupant display in accordance with the travel information acquired by the vehicle information acquisition unit.

  It is conceivable that the vehicle travel information is, for example, information on whether the vehicle is traveling or stopped. However, it is not limited to showing two situations, and it may be divided into multiple stages such as during low-speed driving or high-speed driving.

  In the present invention, based on such traveling information, the content is displayed on the driver display in a mode different from the passenger shared display. In this way, information is provided in a different manner between the “driver display” and the “occupant shared display”, and a plurality of display devices with different information recipients can be fully utilized. As a result, appropriate information can be provided to each occupant.

It is a block diagram which shows schematic structure of a display control apparatus. It is a flowchart which shows a display control process. It is explanatory drawing which shows the production | generation of the content for drivers specifically. It is a flowchart which shows the content delivery process by a center.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
The display control system 1 includes a display control device 10, a vehicle ECU 20, a mobile terminal 30, a center 40, and two displays 50 and 60. One of the two displays 50 and 60 is an occupant display 50 and the other is a driver display 60.

  The passenger shared display 50 is embodied as a rear seat display in which a passenger in the rear seat can be visually recognized or a front seat display in which a passenger in the passenger seat can be visually recognized. The driver display 60 is a display arranged for the driver, and is embodied as a head-up display (hereinafter referred to as “HUD”) or a liquid crystal meter panel.

  Here, the display control apparatus 10 can display the content distributed from the center 40 on the two displays 50 and 60. At this time, the present embodiment is characterized in that the occupant shared display 50 and the driver display 60 can display different modes.

Next, details of each component will be described in order.
The display control device 10 is configured with a control unit 11 as a center. The control unit 11 is connected to a vehicle information acquisition unit 12, a short-range communication unit 13, a data communication unit 14, and two video output units 15 and 16. Hereinafter, the two video output units 15 and 16 are appropriately distinguished as “A video output unit 15” and “B video output unit 16”.

  The control unit 11 is configured as a computer including a CPU, a ROM, a RAM, an I / O, and a bus line connecting them. The control unit 11 displays the content distributed from the center 40 on the two displays 50 and 60 by executing a display control process described later.

  The vehicle information acquisition unit 12 is connected to the vehicle ECU 20 and acquires vehicle information from the vehicle ECU 20. In the present embodiment, vehicle position information and travel information are acquired as vehicle information. An example of the travel information is vehicle speed information.

  The near field communication part 13 is a structure for implement | achieving communication in a vehicle. Here, wireless communication with the mobile terminal 30 is realized. The mobile terminal 30 is embodied as a mobile phone such as a smartphone. Of course, a portable information terminal such as a PDA (Personal Data Assistance) may be used. One of the short-range wireless communication standards is Bluetooth. In the present embodiment, the short-range communication unit 13 is used to acquire visual acuity information as personal information of the driver from the mobile terminal 30.

  In addition, although it was set as the structure provided with the short-distance communication part 13 here, it may replace with the short-range communication part 13 and it is good also as a structure provided with a short-distance communication part. NFC (Near Field Communication) is mentioned as a radio | wireless communication standard of a short distance communication part. In this case, the identification information (ID) of the driver is acquired by bringing the mobile terminal 30 close to the short-range communication unit, and the visual acuity information is read as personal information registered in advance in the display control device 10 based on the ID. To.

  The data communication unit 14 is configured to enable data communication with the center 40 via a network such as the Internet. The data communication unit 14 transmits position information as vehicle information acquired by the vehicle information acquisition unit 12 to the center 40. The center 40 searches and distributes content based on vehicle position information by executing content distribution processing described later. In the present embodiment, facility information such as stores is distributed as content. This content is distributed as HTML content that can be displayed by a browser.

  The A video output unit 15 is configured to output content to the passenger shared display 50, while the B video output unit 16 is configured to output content to the driver display 60. That is, the control unit 11 realizes display in different modes on the two displays 50 and 60 by separately outputting the content via the two video output units 15 and 16.

  Next, display control processing executed by the control unit 11 will be described. This display control process is repeatedly executed by the control unit 11 when the ignition switch of the vehicle is turned on.

  In the first S100, initial display is performed. This process displays, for example, an initial screen that is set as a default, or displays again a screen that was displayed immediately before the ignition switch was turned off, for example.

  In subsequent S110, visual acuity information is acquired. This process acquires visual acuity information from the portable terminal 30 via the short-range communication unit 13. The visual acuity information may be visual acuity (numerical values “0.1” to “2.0”) shown in the visual acuity test table on which the Landolt ring is displayed, or may be a font size setting in the mobile terminal 30. . In the former case, it is assumed that visual acuity is registered in advance in the mobile terminal 30 as personal information.

  In the next S120, vehicle information is acquired. In this process, the vehicle information acquisition unit 12 acquires vehicle information from the vehicle ECU 20. Here, as described above, the vehicle information includes vehicle position information and travel information.

  In continuing S130, position information is transmitted among the vehicle information acquired by S120. In this process, the position information is transmitted to the center 40 via the data communication unit 14. On the other hand, the center 40 searches for content based on vehicle position information and distributes the searched content. This content is facility information such as a store, and is distributed in an HTML language that can be displayed by a browser.

  Therefore, in the next S140, it is determined whether or not the content has been distributed. If it is determined that the content has been distributed (S140: YES), the process proceeds to S150. On the other hand, when it is determined that there is no content distribution (S140: NO), the subsequent processing is not executed and the display control processing is terminated.

  In S150, it is determined whether the vehicle is traveling. This process determines whether or not the vehicle speed is greater than “0” based on the travel information as the vehicle information acquired in S120. If it is determined that the vehicle is traveling (S150: YES), the process proceeds to S160. On the other hand, when it is determined that the vehicle is not traveling (S150: NO), that is, when the vehicle is stopped, the process proceeds to S190.

  In S160, which is shifted to when it is determined that the vehicle is running, content is generated. In this process, content to be displayed on the driver display 60 is generated based on the HTML content distributed from the center 40. As an example, as shown in FIG. 3, it is conceivable to generate the content by acquiring the “title” and “description” included in the header of the HTML content. In FIG. 3, the title tag is “Teppanyaki Kariya store” (see symbol A), and the meta tag description is “Teppanyaki famous for being delicious in Kariya” (see symbol B). Therefore, a text-only content is generated from such information.

  In continuing S170, it is judged whether there exists visual acuity information. Here, an affirmative determination is made when visual acuity information is acquired in S110. If it is determined that there is visual acuity information (S170: YES), the font size is adjusted in S180, and the process proceeds to S190. On the other hand, when it is determined that there is no visual acuity information (S170: NO), the process of S180 is not executed and the process proceeds to S190.

  In S190, the driver display 60 is updated. In this process, content is output to the driver display 60 via the B video output unit 16. At this time, if an affirmative determination is made in S150, that is, if the vehicle is running, the content of only the “title” and “description” text generated in S160 is displayed on the display. For example, in the example of FIG. 3, the text display “Teppanyaki Kariya store” and “It is a famous Teppanyaki delicious in Kariya” is performed. If the font size has been adjusted in S180, the adjusted font size is displayed. On the other hand, when a negative determination is made in S150, that is, when the vehicle is stopped, the content distributed from the center 40 is displayed as it is.

  In S200, the passenger shared display 50 is updated. In this process, content is output to the occupant display 50 via the A video output unit 15. Here, the content distributed from the center 40 is displayed as it is.

  Next, content distribution processing executed in the center 40 will be described. This content distribution process is repeatedly executed at predetermined time intervals.

  In the first S300, it is determined whether or not position information has been received. This process corresponds to S130 in FIG. If it is determined that the position information has been received (S300: YES), the process proceeds to S310. On the other hand, when it is determined that the position information has not been received (S300: NO), the subsequent process is not executed and the content distribution process is terminated.

  In S310, the content is searched for based on the position information. For example, content related to a facility such as a store around a vehicle is searched. Specifically, the center 40 manages facilities in association with maps, and has a database of HTML contents corresponding to the facilities.

  In the next S320, it is determined whether or not there is content. If it is determined that there is content (S320: YES), the content is distributed in S330, and then the content distribution process is terminated. On the other hand, when it is determined that there is no content (S320: NO), the processing of S330 is not executed and the content distribution processing is terminated.

Next, the effect which the display control system 1 of this embodiment exhibits is demonstrated.
In the present embodiment, when content is distributed from the center 40 (S140 in FIG. 2: YES), driver content is generated (S160), and the driver display is different from the passenger shared display. The content is displayed (S190, S200). As a result, information is provided in a different manner between the driver display 60 and the occupant display 50, and a plurality of display devices with different information recipients can be fully utilized. As a result, appropriate information can be provided to each occupant.

  Specifically, when it is determined from the travel information acquired by the vehicle information acquisition unit 12 that the vehicle is traveling (S150 in FIG. 2: YES), the display is for the driver display 60. The content for the driver whose amount of information is reduced is generated and displayed from the current content (S160, S190). For example, as shown in FIG. 3, a text-only content in which “title” and “description” are extracted from the HTML content is generated and displayed. As a result, since the content with the reduced amount of information is displayed for the driving driver, the content can be provided in a manner that is easy for the driver to grasp.

  More specifically, when it is determined that the vehicle is traveling from the travel information acquired by the vehicle information acquisition unit 12 (S150 in FIG. 2), the vehicle is displayed on the passenger shared display 50. The displayed content is displayed as it is (S200). Accordingly, since the display target content is displayed as it is to the passenger even while traveling, it is possible to provide content with a sufficient amount of information to the passenger.

  More specifically, when it is determined from the travel information acquired by the vehicle information acquisition unit 12 that the vehicle is stopped (S150: NO in FIG. 2), the driver display 60 and the passenger shared display 50 are displayed. In both cases, the content to be displayed is displayed as it is (S190, S200). Accordingly, since the display target content is displayed as it is when the vehicle is stopped, it is possible to provide content with a sufficient amount of information to each occupant.

  In this embodiment, the data communication unit 14 that enables communication with the external center 40 via the network is provided, and the display target content is acquired via the data communication unit 14 (FIG. 2). S140). Thereby, various display target contents can be acquired.

  At this time, the vehicle information acquired by the vehicle information acquisition unit 12 includes vehicle position information, and the position information is transmitted to the center 40 (S130 in FIG. 2). On the other hand, when receiving the position information (S300 in FIG. 4), the center 40 searches for the content with the position information (S310), and when the content is searched (S320: YES), distributes the content (S330). ). Therefore, the control unit 11 acquires the display target content transmitted from the center 40 via the data communication unit 14. Thereby, the display target content according to the position information of the vehicle can be acquired.

  Furthermore, in this embodiment, the short range communication part 13 which enables communication with the portable terminal 30 in a vehicle is provided, and the control part 11 is a driver acquired via the short range communication part 13. Based on the visual acuity information (S110 in FIG. 2), the content with the adjusted font size is displayed on the driver display 60 (S170: YES, S180, S190). Thus, since the content with the adjusted font size is displayed on the driver display 60, the content can be provided in a manner that is easily understood by the driver.

As described above, the present invention is not limited to the above-described embodiment, and can be implemented in various forms without departing from the technical scope thereof.
(A) Although the content from the center 40 is described in HTML in the above embodiment, the content is not limited to that described in HTML. For example, any information having a predetermined data structure may be used.

  (B) In the above embodiment, an example of the travel information is vehicle speed information. However, since it is only necessary to determine whether the vehicle is traveling or stopped, information on the shift position may be used, and information on the brake pedal and the side brake is used. May be. Of course, as described above, traveling information is managed in multiple stages, such as during low-speed traveling or high-speed traveling, and the content mode displayed on the driver display 60 during low-speed traveling or during high-speed traveling may be changed. Good.

  (C) In the above embodiment, text-only content consisting of both “title” and “description” is generated as driver content (S160 in FIG. 2). It is also possible to generate content only for “writing”. Further, “summary” may be generated from a sentence having a large number of characters such as a text. That is, the driver content only needs to have a reduced amount of information so that the driver can easily grasp it while driving.
